PASTING MECHANISIVI FOR SHOE MACHINERY.

Specification of Letters Patent. Patented Sept.4 10, v1918. i

Application filed December 28, 1915. Serial No. 68,993.

T0 all 'whom t may concern.'

Be it known that I, FRANK E. EwELL, a citizen of the United States, residing at Bridgewater, in the county of Plymouth and State of Massachusetts, have invented certain Improvements in Fasting Mechanism for Shoe Machinery, of which the following description, in connection with the accompanying drawings, is a specification, like reference characters on the drawings indicating like parts in the several figures.

This invention relates to mechanism for applying paste to parts of boots and shoes and is herein shown as embodied in a machine for attaching heels and toplifts.

One object of the present invention is to provide pasteapplying mechanism so constructed and arranged as to be operated in the regular cycle of the machine for applying the desired amount of paste to a blank at the proper time and without requiring attention or effort on the part of the operator.

It is desired to apply paste to the surface of a toplift after a heel has been nailed to the shoe and just before the toplift is spanked upon the projecting ends of the attaching nails. In machines for attaching heels and toplifts it is customary to provide a movable nail loading -device for delivering the attaching nailsv to the nail receiving passages of the die plate. The loading device must be moved preliminarily to each heel attaching operation. One important feature of the present invention consists in paste applying mechanism including a movableV applying device constructed and arranged to be controlled by the movement of the loader.r Such an arrangement is advantageous in that the actuation of the paste applying device is eected by a motion of the operator which is already necessary in the regular operation of the machine so.

that no additional effort is required and the opera-tion of the machine is not delayed. Moreover, by the employment of such mechanism the application of the paste is made' to occur at the most favorable moment in the cycle of the machine; viz., when the heel and toplift have been placed in the holder and just before the attaching operation.

Another feature of the invention, consist in a paste applying device including a movable plate or pad constructed and arranged so that its applying face enters Ythe paste disposed downwardly when the device is 'Y moved into paste receiving position. It results from such an arrangement that the entire paste applying face is coated with paste so'that a uniform quantity of paste will be applied to each lift. this has not always been the case because it is customary to use a viscous paste which flows too slowly to coat the surfaceof an applying' device when dipped into the paste with but short intermissions between' successive attaching operations.

The features above discussed and others incident to the invention will be best understood and appreciated from the` following description of a preferred embodiment thereof selected for purposes of Aillustration Aand shown in the accompanying drawings, inwhich, v Y

Figure l is a view'of portions of a heel attaching machine in which the present invention is embodied; Y

Fig. 2 is a sectional view of parts shown in a portion of Fig. 1, and

Fig. 3 is a view in perspective showinga toplift with a portion of the paste applying device.

The invention is herein illustrated as disclosed in the American Lightning Nailing Machine shown fully in the application of J. H. Pope, Serial No. 81,878, .filed March 3, 1916. It will be apparent, however, that the invention is not limited in its application to this or to any particular type of nailing or attaching machine.

. In the drawings, a portion of the frame 8 .is shown to which is secured a stationary die plate 12 having nail receiving passages 13. Beneath the die plate 12 is disposed a jack 10 for the shoe to be heeled and mechanism, not shown, is provided for elevating the jack to bring the shoe and heel into engagement preliminarily to the attaching operation. The frame 8 is provided with vertical bearings for a pair of side rods 16 which, as shown in the application above mentioned, are arranged to carry a gang of drivers 14.

The attaching nails are supplied to the nail receiving passages 13 of the die plate by a loader or nail carrier 28 mounted to swing in Heretofore a horizontalp'laiie about one of thej'side rods l6. The loader 28 is located initially in its Y.outer position as .shown indotted lines in Fig. 1. .where it is 'readily accessible to be supplied with attaching nails delivered from .any suitable nail distributing mechanism.

The loader is provided witha handle 30 by which it is swung from nail receiving to nail delivering` position by the'operator.S In Fig. l the loader is shown as having moved through about two-thirds of its path toward ,nail delivering position Secured to the rear ofthe die plate 12 'is a plate 18 upon the lower surface vof Awhich is mounted an oscillatory holder for Vheel and 'toplift blanks.

The holder includes a pair oftoplift engaging fingers 24 and a .pair of'heel-engagingngers 26 broth of ywhich are arranged to swing about a stud 22 as an axis.' The-stud 22 is carried by an adjustable slide disposed below the plate 18 and to be regulated in its position from vfron'ttorear by an adjusting screw 20. The

holder Valsoinclude's a flat spankerplate 25 which extends Overthe toplit holding fingers 24 and engages the tread surface of the vtoplift `'from thetiine the latter is presented .tojthe holder until itis removed fromfth'e -machine .withV the shoe at the conclusion of the attaching operation. ItV will be underi stoodthatthe toplift blank is supplied 4to the toplift holding fingers 24 while the latter occupy a position at the front of the machiney beneath the vnail receiving passages 13.V The holder'is then moved by the' operator into the position shown in Fig-.f1 'wherein the heel holding .fingers 26 occupy aposition beneath the nail receiving passages and the toplii't holdingfingers are located in a position. 90O removed from attaching position. y v

. 'The paste reservoir 60 "is mounted upon i the vframe at the'rear of one of the side rods. It' comprises an elongated troughV havino' a cover with a hinged section 62 where y paste maybe suppliedto the reser-l voir.n The inner endof the-'reservoir 60 yis disposed substantially beneath the topliftl when the heel and toplift holder Vis arranged to hold th'e heel blank beneath ,the nail receiving passages. I

The cover of the reservoir 60 is provided `with a bracket 51 in which is-pivoteda lever imam loaderarm 28 aboveV described. t the rear' ofthe die plate 50 are provided bearings for a horizontally 'reciprocating har 38 having an upwardly projecting pin 36 which is arranged to enter a cam yslot 34 'formed in aV cam arm 32 integral with the loader 28. The cam `slot 34 `is so shaped that when the loader 28 swung from nail receiving positiontonail delivery position the bar 38 willV be moved toward lthe left, Fig. 1, during the first part of the movement of the loader and then held at restfwhile the pin-36 moves in asubstantiallyconcentric vportion of the slot. During the latter -part of the return movement of' the loader thebar 38 is moved in the opposite direction. Secured to the leftendofthe slide bar 38 is a downwardly [projecting bracket 40 having an adjustable arm 42 perforated to receive loosely the threaded shank 44. The 'arm 42 of the bracketfmay be movedi' at substantially right angles to the bar138 for purposes ofy adjustment and then clamped in adjusted position.

The shankV 44 Iisyprovided with stop nuts 46 and 48 uponeithersideof' the bracket arm 42. These 4ni'itsa-re set :to afford a-lost-motion connectionbetween the slide bar'38 and .the shank 44 Vland it will'be apparent that i the length ofzthis connection may be adjusted asdesired.

The pasteapplyingplate 58 which is ried by the outer arm ofy the lever 54 has also a. pivotal connection to the'reversing link 56 which -ispivoted toA a lugon the cover of the reservoir 60 to turn about an axis eccentric to the fulcrum of the lever 54. The constructionv and arrangement ofthe link 56 and lever54 is such that the plate 58 is reversed inpositionas the Alever v54is moved from paste receivingto paste applying position. As-shown lin Fig. 2, the Vp-late58 is movedy downwardly into thepas'tein the reservoir() with ,its applying Vface in ad- Vance ordownwardlydispos'ed and is therefore completely coated with paste. When thelever 54 isswung upwardly the position of the plate 58 isreversedand it comesfint'o engagement with the toplift Avdisposed upwardlyv and in substantially horizontalposition. v Y

By arranging'the `face of the Vpaste applying plate5'8to be disposed downwardly as it enters the. paste it will be noted that a rela- A tively small amount of paste in the reservoir will, be suliicient'to entirely coat the face of the applying plate. f Moreover this arrangement permits the applying face to be brought into close lproximity to the bottom of the reservoir.withtheresult that-the paste is applied yuniformly even though its level in the reservoir becomes very low.y

The operation Vof the above mechanism will doubtless be clear from the foregoingV description but may be briefly outlined as follows.` The machine comes to rest after the operator has attachel both `the heel and` toplift to a shoe with the toplift holding fingers 24 at the front. The operato-r then inserts a toplift blank and turns the holder into the position shown in Figs. 1 and 2 of the drawings, thus bringing the toplift into position above the reservoir 60. A heel blank is then placed in the heel holding lingers 26 and nails are supplied to the loader 28. The operator now swings the loader 28 inwardly as indicated by the arrow in Fig. 1 in order to deliver the nails to the nail receiving passages 13. In this movement of the holder the bar 38 is moved to the 'left and the paste applying plate 58 elevated into contact with the underside of the toplift as indicated by dotted lines in Fig. 2. It is held momentarily in contact with the top lift while the pin 36 is in the concentric portion of the slot 34 in the loader. The loader 28 is then moved reversely whereupon the arm 42 of the bracket 40 engages the stop 48 on the shank 44 and swings the paste applying lever 54 downwardly reversing the position of the paste applying plate 58 and bringing it to rest in the paste in the reservoir. The holder is then turned to bring the pasted toplift into attaching position whereupon the cycle may be repeated.

Having thus described my invention, I claim as new and desire to secure by Letters Patent of the United States:
